CONTROLLING MECHANISM.

Be it known that I, WiLLiAM W. CAM- ERoN, a resident of La Crosse, in the county or La Crosse and State of Wisconsin, have invented certain new and useful Improvements in Controlling Mechanism, of which the following is a full, clear, and exact del scription.

r1 he invention relates to lever-operated controlling-mechanism, and more particularly of the type in which a 'primary lever is employed to operate or shift one or more controlling-connections for one or more different devices, for example, in instances where it is desired to render variable-speed gear-mechanism operative'or inoperative by means of a primary lever and a connection which includes an adjusting-lever for setting the variable speed-mechanism to drive at different speeds. p

The invention designs to provide iinproved controlling-mechanism which is capable of general application. A

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawing: Figure 1 is a side elevation of controlling-mechanism embodying the invention. Fig. 2 is an end elevation.

The improved controlling-mechanism comL 4prises a `primary lever 6 which is rigidly secured to a shaft 7, which is mounted in fixed brackets 8, which 'are sustained in any suitable manner. All of the connections to be operated by the lever 6 are connected to shaft 7, which is pivotally movable in brackets 8 and has arms 9 and 10 secured to one of its ends, and has an arm- 13 secured to itsvother end. Rods 11 and 12 areV connected to arms 9 and 10 respectively and are adapted to shift or control devices, which are to be controlled by lever 6. l, A rod 5is pivoted to the distal .end of arm 13, so that said rod will also be operated or controlled by the lever 6, to control another device. In addition to simultaneously shiftin or conjointly controlling devices by ro s 11, 12, and 5 by lever 6 the latter is adapted to control a connection which it is desired to occasionally adjust, such .as a variable-speed driving-mechanism. In the exemplication shown in the drawing, this mechanism coinprises a wheel provided with `gears 14, 15

and 16 with spaces' 17 therebetween, and a .pinion 18 which is adapted `to be shifted into or out of operative relation with respect to any of said gears, being slidably mounted on a shaft 19 which suitable bearings 2Q and 21 pinion slides to cause the pinion to rotate said shaft at different speeds according to the gear with which the pinion meshes. A

By shifting rod 27, the

pinion may be shifted, into engagement with either of thel gears, 14, 15 and 16 to cause the pinion to be driven at diiferentspeeds or into the grooves between the gears, or out-` side of the outer gear 16, to render the pinion inoperative by the drivingwheel. In practice it may be desired to shift the pinion into and out of drivingrelation with the gears respectively, simultaneously with the operation of connection-rods 11, 12 and 5, so' that the gear-mechanism will always be` operated when the primary-lever 6 and said connecting rods are in one of their alternative positions, and ,so the pinion will be out of .driving relation with the gears .when the primary-lever and said connections are in the other of their alternate ositio-ns.

To permit adjustment' o the pinion to vary the speed at which shaft 19 will be driven, an adjusting-lever 28 is included 'in the connection between rod 27 and theprimary shifting element, so that pinion 18 will .be shifted relatively to gears 14, 15, and 16,

by primaryl lever 6 in harmony with the other connections and devices controlled bv said lever while the speed ofthe pinion and shaft driven thereby may be varied as desired by .the adjusting-lever. Adjusting-lever -28'is pivoted on a stud 29, which is eccentrically disposed with respect to the .fulcrum-shaft 7 of the lever 6 and on arm 13, which is rocked by the primary lever. Lever 28 extends below its pivot 29, and is operatively connected to rod 27 and controls the variable-speed driving-mechanism, so as'to effect positive shift of rod 27 in that direction which causes the pinion 18 to be thrown out of engagement with the gears and is yieldingly operated inV the reverse iol .is extended.

. lock adjusting-lever 2,8 1n

direction, to facilitate movement of the pinion into engagement with the gears. A pm 30 onv rod-j 27 is engaged by a lug 31 on lever 28', and a spring 32 coiled around said rod and extending between a lug l31a and a nut 33 on said rod provide such means for operatin rod-27 positively in one direction and yiel ingly in the other. Rod 27 extends loosely through openings in lugs 31, 31a on lever 28. v Lever 28 is shifted bodily by stud 29 when the primary lever 6 is shifted, and the pivotal movement of lever 28 relatively to eccentric connection 29` and arm 13 is controlled by a rack 84 which is also pivoted on stud 29, and is connected to rod 27 by an arm 35, which is rigid with said rack and through the lower` end of which rod 27 A lever lock 36 is-adapted tol different relative positions, with respect' to the primary lever 6` the bolt of this lock being adapted -to enter either of a series of notches 37 in said rack.

In operation, assuming the mechanism to' be in the position illustrated in the' drawings, the pinion 18, will be operative by the lgear 15. When the'Vmain-lever 6 is raised to the position indicated' in dotted lines, shaft 7 will be rocked to operate rods 11, 12 and 5 and'stud 29 will cause the-adjusting-lever 28 and rod 27 to be shiftedA bodily and the primary cated in harmony with 55.

because the movement of adjusting lever 28 will be controlled by the arm 35 which is connected to the controlling-rod 27 Such operation will cause the connecting rod 27 lever 6, including lever 28 to be operated to shift pinion 18 out of engageinent with gear 15 to the position indiby' dotted lines in Fig? 1. Reverse shift or lowering of the lever 6 will shift all of the lconnections including rod 27 to cause pinion 18 to be rengaged with the gear-wheel. When the pinion 18 is to be adjusted to vary the speed of driven shaft 19, adjusting lever 28 will be-unlocked from rack 34and shifted so that the lock 86 will be set into one of the other notches 37 of said rack and resultantly the connection for controlling the variable speedmechanism will be adjusted to cause pinion 18 to be shifted into a 'd out of engagement with either of-the gears 14 16 and then the pinion will be controlled by primary lever 6, the mechanisms controlled by connections 11, 12 and 5.` Thus, the variable speed mechanism will be rendered op- ,erative and inoperative in synchronism with other devices or .mechanism controlled by the primary lever and it is readily adjustable by lever 28, to vary the speed of one of the mechanisms.

The invention thus provides simple controlling mechanism in which there is a priinary lever and a connection, which includes an adjusting lever, and in which the adjustwithin the scope of the appended claims,
